No 23-word album titles a la Fiona Apple for Britney Spears! The "Work Bitch" singer, 31, revealed the title for her forthcoming studio album — her eighth — during an Oct. 14 radio interview in London: Britney Jean.

"It's a personal album, and all my family, they always called me Britney Jean," Spears explained to 95-106 Capital FM. "It's like a term of endearment. I just wanted to share that with my fans."

The followup to 2011's platinum smash Femme Fatale goes on sale Dec. 3, and the mother of two teamed up with the likes of mega-producers will.i.am and frequent Madonna collaborator William Orbit. As for other high-profile guest stars, like, perhaps, Miley Cyrus? "You'll have to wait and see!" she teased of Cyrus, 20, with whom she sang on "Bangerz (SMS)" for the younger starlet's new album.

The end of 2013 and beginning of 2014 promises to be very busy for Spears, who also kicks off her two-year Las Vegas residency at Planet Hollywood Dec. 27. "I'm really stoked about it. I've toured the world so many times and had been in different hotels every night. It's going to be nicee to ahve one place to be at for my children and my family," said Sean and Jayden's mom.

Spears also dished a tad about Sin City downtime with "my boyfriend" David Lucado — and she prefers spas, not gambling. "I love the oxygen facials and I love getting pampered," she revealed. "And the food is amazing! The food's crazy. I always gain, like, 10 pounds when I go. It's ridiculous."
